Python's rookie path: the Django admin background management feature uses

Objective

Children's shoes with the Django framework are sure to know that after the Django project is created, each app will have a urls.py file with the following lines:

From django.contrib import adminurlpatterns = [    url (R ' ^admin/', admin.site.urls),]

See the Import admin module above, that is the main content of this section

Key Features

Feature 1: Provides database management capabilities

Based on the admin module, the function of database client can be realized, and the data is added and censored.

Function 2: two times development

Based on the data management function of the module, some practical functions can be customized two times.

How to use

Step 1: In settings.py, Installed_apps, add django.contrib.admin

Installed_apps = [    ' django.contrib.admin ',    ' Django.contrib.auth ',   #admin依赖    ' Django.contrib.contenttypes ', #admin依赖    ' django.contrib.sessions ',  #admin依赖 ...    ]    

Step 2:urls.py Create the admin route

From django.contrib import adminurlpatterns = [    url (R ' ^admin/', admin.site.urls),    ....   ]

Step 3: In the settings.py configuration file, the middleware registration

middleware = [    ' Django.contrib.sessions.middleware.SessionMiddleware ',    ' Django.middleware.common.CommonMiddleware ',    ' Django.contrib.auth.middleware.AuthenticationMiddleware ',    ....]

Step 4: Create admin administrative user

Python manage.py Createsuperuser

Step 5: Create table information in the app's models.py file, which is the table class

From django.db import Modelsclass Gender (models. Model):    name = models. Charfield (MAX_LENGTH=32) class UserInfo (models. Model):    nid = Models. Autofield (primary_key=true)    name = models. Charfield (max_length=30, verbose_name= ' username ', editable=false)    email = models. Emailfield (db_index=true)    memo = models. TextField ()    img = models. ImageField (upload_to= ' upload ')    User_type = models. ForeignKey ("Usertype", Null=true, blank=true)    gender_choices = (        (0, "male"),        (1, "female"),    gender = Models. Integerfield (Choices=gender_choices,default=1) class usertype (models. Model):    name = models. Charfield (max_length=32)    def __str__ (self):        return Self.name

Step 6: Register the table in admin.py

From Django.contrib import admin# Register your models here.from app01 import modelsadmin.site.register (models.userinfo) Admin.site.register (models. usertype)

Step 7: Build the table structure

Python  manage.py makemigrations && python manage.py migrate

Step 8: Run the project, login to the management interface

Python manage.py runserver Access url:http://ip:8000/admin
